Highband Balanced
Modulator Input
The input to the Balanced Modulator of the
Upperband limit. This input must be connected to
the Highband Filter Output via capacitor C5. See
Figure 2 and Figure 3.
The input to the Balanced Modulator of the
Lowerband limit. This input must be connected to
the Lowband Filter Output via capacitor C6. See
Figure 2 and Figure 3.
This analog ‘Clear’ audio input for the VSB
Scrambler. This pin is held at a DC ‘bias’ voltage by
a 300k on-chip bias resistor, which is selected for
all functions except powersave. In must be
connected to external circuitry by capacitor C4. See
Figure 2 and Figure 3. This input, in Tx mode, is
connected to Upper and Lowerband input filters.
Signal paths and bias levels are detailed in Table 2
and Figure 6.
The output of the Input filter of the lowerband limit.
The
Tx
/
Rx
function determines which filter is used
(Filter 1 or 2). See Figure 6 and Figure 7. This
output must be connected to the Lowband balanced
modulator input via capacitor C6. See Figure 7.
A single 5.0V supply is required.
